  I will request features on forum or via support.
• [ x] I've searched and did not find a similar issue.

Describe the bug
I get the same issue reported by "https://www.reddit.com/r/tutanota/comments/1daxecf/im_having_trouble_logging_into_my_tuta_account/"
Hello,
when I launch the “Tutanota Desktop” application, the inscription on the button is “Add Account” instead of Connexion.
If this button is clicked, the program carries out an action that was not planned and is therefore suspicious without accessing the messaging system.
On the other hand, when I go to the site, “https://mail.tutanota.com/login” or “https://app.tuta.com/login”, the button registration is correct and everything works properly.
Updates to the Tutanota Desktop application are automatic and regular.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Tutanota Desktop'
2. Click on 'Add Account'
3. Don't open messaging system.
